METHOD FOR FORMING UNIFORM AQUEOUS FILM TO TPO SHEET FOR CAR INTERIOR MATERIAL AND AQUEOUS SURFACE TREATMENT AGENT FOR IT

摘要

PURPOSE: A method for forming uniform aqueous film to TPO sheet for car interior material and aqueous surface treatment agent for the same are provided to reduce the smell generated in the inside of vehicle and to obtain the VOC reduction effect. CONSTITUTION: The method for forming uniform aqueous film to TPO sheet for car interior material and aqueous surface treatment agent for the same comprises as follows. The waterborne primer is coated in the TPO sheet for the automobile interior finish with gravure. The aqueous surface treating agent is coated with spray after the aqueous surface treating agent is coated in the sheet coated with primer with gravure. The viscosity of the waterborne primer is 800~1,000 cp. The viscosity of the aqueous surface treating agent includes the urethane resin and is 800~1,000 cps.
